Iowa's Luka Garza is The Associated Press player of the year in the Big Ten Conference and Wisconsin's Greg Gard is its coach of the year.
Garza was the unanimous pick for player of the year and for a spot on the AP's All-Big Ten team, also announced Tuesday, in voting of 15 journalists covering the conference.
Illinois's Kofi Cockburn was named newcomer of the year.
Winston, the 2019 player of the year, is a repeat selection to the first team. Stevens was a second-team pick last year.
Garza, a 6-foot-11, 260-pound center from Washington, D.C., has scored 20 or more points in his last 16 games, the longest streak by an Iowa player since 1971.
He has scored 25 points or more 13 times this season and has seven games with at least 25 points and 10 rebounds. His 15 double-doubles are the most by an Iowa player since 2002. His 23.9 points per game rank fifth nationally, and his 26.2-point average in conference games is the highest since Purdue's Glenn Robinson averaged 31.1 in 1994.
Cockburn, a 7-foot, 290-pound freshman from Kingston, Jamaica, averaged 13.8 points, 8.8 rebounds and 1.4 blocks. He blocked a shot by Garza under the basket at the buzzer to secure a 78-76 win Sunday that gave Illinois the coveted No. 4 seed, and double-bye, for the Big Ten Tournament.
Under Gard, Wisconsin won 16 of 21 games after a 5-5 start to finish 21-10 overall and 14-6 in the Big Ten. The Badgers shared the regular-season title with Michigan State and Maryland after winning eight straight games, the program's longest win streak to end the regular season since 1940-41.
